Corrections and clarifications

• The heading on yesterday's news story about proceedings at the inquiry into Britain's involvement in the Iraq conflict – UK troops were 'sitting ducks' in Basra, inquiry told, page 14, and guardian.co.uk – implied that this description came from the commander-in-chief of British land forces, Peter Wall, who was appearing before the inquiry. The phrase originated in a question from a member of the inquiry panel, Roderic Lyne, who asked if the troops at the Basra base were sitting ducks. As the story said, Peter Wall replied "yup". Our story was updated when he later contacted our reporter to say that his "yup" was not meant to agree with this description of troops but to acknowledge that it had been used in the past. The headline remained in place.

• In a story about footprints made by a four-legged creature long ago, a Cambridge palaeontologist, Jenny Clack, was misnamed as Jenny Clark (A small step for tetrapods, 7 January, page 11).

• A brief comment piece said that there are now three members of the European parliament from the British National party. There are two (I changed my mind about…, 1 January, page 28).

• In a feature where journalists do a bit of work experience at jobs they've always fancied, a landscape gardener, Chris O'Donoghue, was misspelled as O'Donohughe (Their brilliant new careers, 4 January, page 5, G2).
